COVID prohibition logic

The German court in Berlin said that any ban (the ban on alcohol shops selling at certain hours of the night) must have:

(A) at least a recognisable advantage (Erkennbaren Nutzen)
(B) to prevent or limit the INCREASED spread of the epidemic).

The German court considered that the prohibition on the sale at certain times (at night) introduced by the local authorities in Berlin did not have such an advantage and lifted the prohibition.
Applying this method to Polish bans at first glance, it seems that the ban on dancing at weddings has such an advantage. In dance, the spread is greater than without dance. But the key should be a reference to the average of infections in general. And not just a comparison of infections in dance and infections without dancing. Whenever we do something socially, it will encourage the development of Sars more than when we do nothing. Nevertheless, we do not close everything and everywhere. You need to compare the infection data in the dance with the average of infections in general. So did data in fitness clubs with average infections in general and not with the condition that would have been if the clubs hadn’t been closed. Causal link in itself is not sufficient. In Poland, too, this time we have problems with logic.
